The NIH Adult Respiratory Distress Syndrome (ARDS) Network developed a ventilator strategy using a lower tidal volume. The patient can be weaned once certain criteria are met.


Weaning criteria - all of the following should be present:

(1) FIO2 < 0.4

(2) PEEP < 8 cm H2O

(3) systolic blood pressure > 90 mm Hg

(4) The patient is not receiving neuromuscular blocking agents.

(5) The patient is not receiving vasopressors.

(6) The patient is making inspiratory efforts.



• Inspiratory effort can be detected by watching the patient for 5 minutes after decreasing the ventilator rate to 50% of baseline.
